Senior Backend Engineer · Microservices · Distributed Systems · Event-Driven Architecture
Hi, I'm Amit. I'm a backend engineer with 10+ years of building Java and Spring Boot microservices: Kafka event flows, Saga transactions, API gateways and the kind of systems that have to keep working when things fail.
I started Compiled Canvas because most tech topics are taught as a wall of text and code. I'd rather show you the idea moving on screen first and write the code after. DSA in Java is live now, and Java, AI for developers, Python, SQL, Spring Boot, system design and interview prep are next. Every course gets the same treatment: short videos, then practice right here.
